Wikimedia Commons is a repository of free images, videos, sounds and other multimedia files. Uploaded files can be used as local files by other projects on the Wikimedia servers, including Wikibooks, Wikinews, Wikipedia, Wikiquote, Wikisource, Wikiversity, Wikivoyage, and Wiktionary. The InstantCommons feature also supports imports on other Wikis.
This page is an index of all Wikimedia' maintenance and pages. The following articles contain guidance and information about reading, authoring, and participating in the Commons community.
Help page collections
A larger set of help pages can be found in Wikipedia that you might want to consult:
The function of MediaWiki itself (the software of Wikimedia Commons) is described at the MediaWiki User's Guide in Meta-wiki. The MediaWiki-handbook in Meta-wiki is not kept here in order to avoid duplicate maintenance work (the same applies to all help pages not specific to Wikimedia Commons).
If you suspect a software bug, ask for feedback at the village pump, and then report it using the Bugzilla bug report system. This is the only way to get MediaWiki developers to notice your bug reports.
The database of Wikimedia Commons can be downloaded. Sadly the available dumps are only the database text. There is currently no dump of the media files available.
